Coan and Kaz both wore squat suits, and knee wraps, but no bench shirts early on(Although late in his career Coan has worn a bench shirt).
Coan's best USAPL/IPF squat was 1003 @ 242 and best deadlift was 903 at 218!!!
He also benched 573 without a bench shirt.
Kaz squatted in the 900s, deadlifted in the very high 800s and benched 661 without a shirt.
Brian Siders is a complete animal, but the single ply squats suits of today and the becnh shirts of today, cannot be compared to what Kaz and Coan wore. Brian weighs 330 and still has not touched Coans Squat or Deadlift numbers, although with todays bench shirt Siders destroys Kaz and Coan, but with that you cant really compare. But all three of these guys lifted and lift in flawless fashion, which does not exist in todays superply monolift feds.
